CORN-SHELLER.

Specification of Letters Patent.

Patented J an. 30, 1912.

Application filed September 7, 1911. Serial No. 648,103.

To all whom t may concern.'

Be it known that I, SALVADOR ORDEz, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Corn- Shellers, of which the following is a specification.

separating the dust and chaff from the shelled grain.

The further object of my invention is the provision in a device of this character of improved means for preventing clogging of the machine.

Other objects and advantages of my improved corn sheller will be readily apparent by reference to the following description taken in connection with the accompanying drawings, and it will be understood that I may make any modifications in the specific structure shown and described within the scope of my claim without departing from or exceeding the spirit of my invention.

Figure 1 represents a side elevation of my complete sheller. Fig. 2 represents a top plan view of my sheller. Fig. 3 represents a longitudinal sectional view thereof, and Fig. 4 represents a vert-ical sectional view on the line 4-4 of Fig. 1.

In the drawings, the numeral 1 designates the main supporting legs or standards of my corn sheller which are connected by the longitudinal beams 2 and transverse beams 3 providing the main frame work of my sheller. Journaled in the bearings 4 at one end of the uppermost beam 2 is a shaft 5 bearing a roller 6 having secured on one of its projecting ends the large pulley 7 and the smaller pulley 8. Bearings 9 are slidably engaged in slots 10 formed in the other end of the beam and are held in adjusted position by the set screw members 11. .Iournaled in the bearings 9 is a shaft 12 bearing a roller 13. An endless belt 14 passes around the rollers 6 and 13 and has secured thereon the transversely extending strips 15 of wood or other suitable material having their upper portions cut to form the shelling teeth 16. The medial longitudinal braces 2 likewise support at one end stationary bearings 17 for the shaft 18 of the roller 19 and adjustable bearings 20 for the shaft 21 of the roller 22, said shaft 21 havlng a projecting end on which is secured the small pulley 25. A second endless belt 24 passes around the rollers 19 and 22 and ,has the strips 15 providing teeth 16 secured thereto. To resiliently support the central part of the belt 24 and prevent the same v from sagging, I form in the inner face of My invention relates to improvements in corn shellers, and has for its leading object the provision of improved mechanism forv rapidly and automatically shelling corn and the intermediate longitudinal braces recesses 25 in which are slidably supported the bearings 26 forced upward by the spring 27. Rollers 28 have their shafts 29 journaled in said bearings and are resiliently forced upward by the springs to hold the teeth of the belt 24 near the teeth of the belt 14 but permitting of downward movement of the belt 24 when the device clogs to prevent breaking of the machine.

In order that corn on the ear'may be readily fed onto the belt 24 whichv extends farther to the front and rear than the belt 14, I secure to the front standards 1 the chute or guide trough 30, while to prevent falling off of the. ears after they have once been deposited on the belt, -I preferably inclose the sides of the frame with a casing Y20 while leading from the pulley 32 is a belt 38 passing around the pulley 7 on the shaft 5, the different pulleys being of such size that the belt 24 will be driven at about three times the speed at which the belt 14 is driven, the two belts moving in the same direction so that their contiguous portions are moving in opposite directions. This movement will cause the ears of corn from the chute 30 to be carried along on the belt 24 while grated or rubbed and somewhat turned by the teeth of the belt 14 which will serve in connection with the teeth of the belt 24 to thoroughly shell the corn. To aid in the turning and shifting of the various ears of corn,..I secure to the belts 14 and 24 between certain of the strips 15 the flexible steel plates 39 which project a sufficient distance to interengage with each other and tightly bear against the ears to insure turning thereof while yielding sufficiently to allow the ears to pass by the same.

To receive the grain and cobs from the rear of the belt 24 and to satisfactorily separate the same I secure to the rear standard l the beams having their rear ends secured to the legs or posts 4l. Connecting said posts 4l is the rod 42 on which is pivotally secured the metal plate or screen 43 having the perforations 44 therein of size to permit of the ready passage of the grain therethrough. Said plate inclines forwardly and upwardly and has its front end disposed adjacent the roller 19 and resting on the cam fingers or wipers 45 which are secured on the shaft 4G. Said shaft bears the small pulley 47 connected by the belt 48 with the pulley 8 on the shaft 5, whereby as the belt 38 causes the rotation of the shaft 5 the shaft 46 will be rotated and the wipers will shake the screen 43 on its pivot rod 42. This movement will tend to shake down the grain and chaff through the openings in the sieve plate while the cobs will slide down over the plate and fall olf of its lower end.

Ordinarily the grain and chaff would drop together, but I have provided means for separating the two to cause only the grain to drop into the trough 49 of the inclined plate 50 disposed below the screen plate 43. Inclosing the sides of the i'ear supplemental frame and extending from the plate 50 above the plate 43 are the side plates 5l, the plates 50 and 51 extending forward to form the rounding fan casing 52. Journaled in the fan casing 52 is the shaft 53 bearing the vanes 54 and having on one end the pulley 55 connected by the crossed belt 56 with the pulley 33 of the shaft 32. This fan serves when the machine is in operation to cause a strong draft between the plates 51 and 43 which blows out all of the light chaff through thespace 57 between the rear edges of the plates 43 and 5() while the heavier grain slides down the plate 50 into the trough 49.

From the foregoing description taken in connection with the accompanying drawings the construction of my improved corn shelling machine will be readily understood, and it will be seen that I have provided an extremely simple and eflicientmachine which will receive the full ears of corn and as it conveys the same therethrough will thoroughly shell the corn and will afterward separate the shelled corn from both the cobs and from the chaff and which is capable of operation at various speeds according to the amount of corn which it is desired to shell in a given time.

I claim:

A corn sheller comprising a frame, a pair of upper and lower rollers supported thereby, a belt passing around each pair of rollers, said belts being spaced apart and having confronting surfaces adapted to move in opposite directions, resiliently supported rollers arranged between the lower pair of rollers and adapted to yieldingly support the lower belt, teeth projecting from the belts, a plurality of spaced flexible plates carried by said belts and arranged transversely thereof, said plates being adapted to engage and disengage upon the confronting faces of the belts during their travel in opposite directions, whereby the ears of corn are turned during the shelling operation.

`In testimony whereof I affix my signature, in the presence of two witnesses.

SALVADOR ORDOEZ. Witnesses J. A. Lowmn, A. Lowiuii.
